1) Pretty much what Blitz said (show us the 3d view if you show anything, we can't project the 2d views in our heads), but:
2) that looks FAAAAAR too big (if you can see the edges of the grid, that's quite enough)
3) Select all and move everything down so that the origin (where the blue grid lines cross) is inside your box. That should spawn players there until you have info_player_teamspawns. You may be currently spawning inside a brush, which would either get you stuck or drop you through it.
